Experiment on Water Mist Fire Suppression in Long and Narrow Spaces

摘要：

Based on the effects of longitudinal ventilation on fire behavior and droplet movement respectively, simulative studies on water mist fire suppression were performed. Scaling relations for water mist fire suppression has been derived to include forced longitudinal ventilation, for the guidance to determine the design of reduced-scale experimental model. A series of fire suppression experiments were carried through set-up construction. The effects of different actors, including water mist characteristics, longitudinal ventilation rate and fire size on the performance of water mist under longitudinal ventilation in the long and narrow spaces were studied systematically. There was good agreement of the normalized temperature distribution between the reduced scale and the full scale experiments. This suggests that the scaling techniques can be used with confidence to predict the the temperature distribution for larger-scale long and narrow spaces.
